Drivers and Applications

GTK+ UVC Viewer

The GTK+ UVC Viewer[1] (guvcview) a simple GTK interface for capturing and viewing video from devices supported by the linux UVC driver. It works great with the Logitech QuickCam Pro 9000 and seems to support all features of the camera.

When the camera is used for the first time after boot, one has to execute

$> sudo guvcview -a

to detect and add all the supported controls. Note: this may not be necessary if libwebcam is installed (TBC).

Gstreamer

Windows

After installation, the software that comes with the camera works well and can capture HD-like video very well. However, when using a third party capture application, size seems to be stuck at 320x240 pixels.

Mac

Camera seems to work but stuck on 320x240 and no way to control settings. I couldn't find any useful app for Mac.

Autofocus

Autofocus is built into the wintendo drives, thus does not work in Linux.

Q: How can we manually control focus in Linux?
A: Yes, guvcview can control focus and also has autofocus functionality

Lens

According to the specs the camera has a Zeiss lens[6]. Although it is quite all right compared to other webcams, the image lacks sharpness around the edges and this is very visible and annoying on outdoor pictures:

The above image was taken on Linux using Guvcview; however, the problem also exists when using the windows software that came with the camera:
